Downloading LOTRO Game Client help

Hi! I am future player of the game The Lord of the Rings Online: Shadows of Angmar, and I would like to test it first with buddy key, and after that buy the game if I like it. how can I download Game Client and where can I find it? I have 512MB at this time, should I buy more memory? Thanks in advance for answering my questions.

The download copy of the game The Lord of the Rings Online: Shadows of Angmar is low resolution version of the retail copy and it's mainly created for the people who have a buddy key or have some problem with DVD disc they bought. If you are running below 512MB of memory, you should run in Low or Very Low graphics mode or you will experience a lot of memory thrashing and bad presentation. You can download a The Lord of the Rings Online: Shadows of Angmar Client from site of the developer, Turbine, Inc.
